How do i solve and what is the answer

I and III

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

• Parallel lines have equal slopes

I y = 4x → m = 4

II

y = - x + 2 → m = -

III

rearrange 12x - 3y = 6 into slope- intercept form

subtract 12x from both sides

- 3y = - 12x + 6 ( divide all terms by - 3 )

y = 4x - 2 → m = 4

IV

rearrange into slope- intercept form

4(y + 6) = x - 3

4y + 24 = x - 3 ( subtract 24 from both sides )

4y = x - 27 ( divide all terms by 4 )

y = x - → m =

I and II have the same slope, hence are parallel lines

answer: i would say b

step-by-step explanation:

with the way the question is worded, i believe b is the answer

the cost of the apple depends on the weight

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
